Descrição geral

Sodium carboxymethyl cellulose (CMC) is a water dispersible sodium salt of carboxy-methyl ether of cellulose that forms a clear colloidal solution. It is a hygroscopic material that has the ability to absorb more than 50% of water at high humidity. It is also a natural polymeric derivative that can be used in detergents, food and textile industries.[1][2]

Aplicação

CMC can be used to stabilize palladized iron nanoparticles, which can further be utilized in the dichlorination of contaminated subsurfaces.[3] It may also be used as a polymeric matrix to form a composite with a crystalline nanofibril for the development of sustainable bio-based polymers.[4] CMC can also bind with a hard carbon electrode for the fabrication of sodium ion-batteries.[5]
